Hillary Clinton yesterday demanded that Mayor Giuliani “disavow his arch-conservative allies” while the mayor charged the first lady with fibbing about how much money she’s raised.

Using levels of rhetoric that are typically not heard until Labor Day, campaign aides pulled out all the stops to make their opponents look sleazy and dishonest.

Standing in City Hall Park, Clinton campaign manager Bill de Blasio called on Giuliani to contact conservative groups waging direct-mail fund-raising campaigns against the first lady.

“Tell your friends on the far right to stop their campaign of lies and deceit,” said de Blasio, who compiled a 38-page packet of conservative fund-raising letters he titled “The Hillary Rodham Clinton Truth Campaign.”

Speaking to reporters in City Hall, Giuliani said Clinton’s aides “are pointing to literature from other organizations that I have no connection with and they are trying very artfully to get you to create an issue that doesn’t exist.”

Giuliani artfully tried to make the most of the fact that Clinton’s campaign committee directly raised $6.86 million last year while bringing in an additional $1.16 million at other fund-raising events. Those fund-raisers were for Clinton in conjunction with Democratic state and national campaign committees.

Clinton’s advisers last month said she had raised $8 million — without breaking down the figures.

Clinton communications director Howard Wolfson shot back: “It sounds like the mayor is having a tantrum over a very typical accounting device. Maybe he’s embarrassed at himself for not knowing who Joerg Haider is.”

Haider, a rightist Austrian leader who has praised Nazi policies, was one of 80 people who shared the dais with the mayor at a Congress of Racial Equality dinner last month.

For the first time, Giuliani addressed the issue, saying he didn’t know who Haider was when he shook hands with him.

Asked if he would have attended the dinner knowing Haider’s pro-Nazi past, the mayor replied: “I guess if I knew what I know now, no, I probably wouldn’t have. But at the time I had no idea who he was. I go to a lot of dinners.”

Along with his condemnation of Haider, Giuliani’s schedule yesterday would have pleased many Jewish voters.

In the morning, he attended a matzo-ball-eating contest at a Kosher deli. Later in the day, he joined leaders of the Russian Orthodox Church in attacking Yasser Arafat for giving Russians a West Bank monastery.
